Pangea: an "all land" continent - a super continent that existed 300 million years ago.
Continental drift: the movement of continents over time.
Fossil: trace of an organism that has been preserved in rock.
Outline
Topic=Drifting Continents
Summary - Africa and South America look like they fit together like a puzzle.
Theory of continental drift:
1910/ Wagenar
hypothesis of single landmass/ Pangea
suppported ideas with the study of landforms, fossils, and climate
evidence from landforms=used mountains, Africa, and South America
evidence from fossils= coal fields, common fossils found at distant country
evidence from climate= continents today have very different climates than million of years ago
Scientists reject Wagener's theory:
couldn't prove how continents drifted
